Product details
Overview
PTVS24VP1UTP-QX from Nexperia is a unidirectional 600 W Transient Voltage Suppressor (TVS) in SOD128 (CFP5) package, designed for high-temperature overvoltage protection in automotive power rails. Confirmed parameters: VRWM = 24 V, VBR(min) = 26.7 V, VCL(max) = 38.9 V at IPPM = 15.4 A, Tj ≤ 185 °C, and AEC-Q101 qualified.
For engineers reviewing the PTVS24VP1UTP-QX datasheet, PTVS24VP1UTP-QX pinout, PTVS24VP1UTP-QX application, or PTVS24VP1UTP-QX equivalent, this page delivers verified electrical specs, thermal behavior at elevated junction temperatures, clamping performance under IEC 61643-321 10/1000 µs transients, and automotive-grade reliability validation.
Technical Context
This TVS diode operates in avalanche breakdown mode to clamp transient surges above its reverse standoff voltage (VRWM = 24 V), with a minimum breakdown voltage of 26.7 V at 1 mA. Its unidirectional configuration protects DC power lines against positive-going transients only, requiring correct anode–cathode orientation relative to system ground.
Thermal design is critical: Rth(j-a) ranges from 60 K/W (ceramic PCB) to 200 K/W (standard FR4), and rated peak pulse power de-rates linearly above 25 °C - maintaining 600 W only up to Tj = 25 °C and dropping to ~480 W at Tj = 125 °C per Fig. 2.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRWM | 24 V - Maximum continuous reverse operating voltage before clamping begins; defines safe DC rail margin. |
| VBR (min) | 26.7 V - Minimum breakdown voltage at 1 mA; ensures reliable turn-on above normal operating voltage. |
| VCL (max) | 38.9 V - Maximum clamped voltage at IPPM = 15.4 A; determines protected circuit's peak stress during surge. |
| PPPM | 600 W - Peak pulse power handling per IEC 61643-321 (10/1000 µs); defines single-event surge energy capacity. |
| IRM | 0.001 µA - Reverse leakage at VRWM; negligible current draw in standby, preserving low-power system integrity. |
| Tj max | 185 °C - Maximum junction temperature; enables operation in under-hood automotive environments without derating. |
| AEC-Q101 | Qualified - Validated for automotive discrete semiconductor stress testing; supports ASIL-B system-level compliance paths. |
Pinout & Package
PTVS24VP1UTP-QX uses the CFP5 (SOD128) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm lead pitch, flat lead profile optimized for reflow soldering and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to protected line (e.g., +12 V rail); marking bar identifies this terminal; carries surge current into ground path. |
| 2 | Anode (A) | Connected to system ground; completes conduction path during transient; must be low-inductance for effective clamping. |
Key Features
| Feature | Design Value |
|---|---|
| High-temperature stability | Operates reliably up to Tj = 185 °C - eliminates thermal derating in engine control units and ADAS modules. |
| Low-profile SMD package | 1.0 mm height - enables placement beneath connectors or in stacked PCB assemblies without mechanical interference. |
| Automotive qualification | AEC-Q101 certified - meets stress test requirements for vibration, temperature cycling, and HBM ESD (8 kV), reducing qualification effort. |
| Low leakage current | IRM = 0.001 µA at VRWM - prevents battery drain in always-on vehicle networks (e.g., CAN wake-up circuits). |
| Controlled clamping ratio | VCL/VBR ≈ 1.45 - balances low clamping voltage against robustness; avoids false triggering while limiting downstream IC stress. |
Applications
| Engine Control Unit (ECU) Power Input | ADAS Camera Module Supply Rail |
|---|---|
Use Scenario: Protects 12 V input of gasoline/diesel ECU against load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between battery feed and input filter capacitor; conducts within nanoseconds of overvoltage onset. Use Value: Clamps transients to ≤38.9 V, preventing damage to MCU power management ICs rated for 40 V absolute maximum. | Use Scenario: Shields 5 V/3.3 V camera module supply from coupled noise and ESD events in rear-view or surround-view systems. IC Role / Device Role / Timing Role: Secondary protection stage after common-mode choke; absorbs fast ESD bursts (IEC 61000-4-2 ±30 kV contact). Use Value: Sub-µA leakage preserves sleep-mode current budget; 185 °C rating supports operation near hot image sensors. |
| Electric Power Steering (EPS) Motor Driver | Body Control Module (BCM) LIN Bus Line |
Use Scenario: Guards high-side FET gate driver supply against inductive kickback from brushed DC motor commutation. IC Role / Device Role / Timing Role: TVS connected across VDD and GND of gate driver IC; activated during 100 ns–1 µs voltage spikes. Use Value: 600 W pulse rating handles repetitive switching surges; SOD128 footprint allows placement adjacent to driver IC for minimal loop inductance. | Use Scenario: Protects LIN transceiver I/O pins from cable discharge and board-level ESD in door modules and seat controllers. IC Role / Device Role / Timing Role: Bidirectional protection not required - unidirectional device used on VBAT-supplied LIN line with proper polarity. Use Value: 24 V VRWM matches typical LIN VBAT range; AEC-Q101 qualification ensures long-term reliability in 15-year vehicle lifecycle. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ24A-Q | Same VRWM (24 V), but lower PPPM = 400 W; higher VCL = 39.4 V; SMC (DO-214AB) package (2.5 mm height). | Less suitable for high-energy load dump; taller profile limits use in ultra-thin modules. | Select when cost sensitivity outweighs pulse energy requirement and board height is unconstrained. |
| TPSMA6L24 | VRWM = 24 V, PPPM = 600 W, but Tj max = 150 °C; no AEC-Q101 qualification; SMA package (2.2 mm height). | Not validated for automotive under-hood use; requires additional qualification effort for OEM deployment. | Acceptable for industrial power supplies where ambient temperature stays below 105 °C. |
Compared with SMAJ24A-Q and TPSMA6L24, PTVS24VP1UTP-QX uniquely combines 600 W pulse rating, 185 °C junction capability, and AEC-Q101 qualification in a 1 mm profile - making it the only drop-in solution for next-generation automotive ECUs demanding compact, high-temperature surge immunity.

FAQ
What is the maximum clamping voltage for PTVS24VP1UTP-QX under full-rated surge current?
The maximum clamping voltage (VCL) is 38.9 V at IPPM = 15.4 A, measured per IEC 61643-321 10/1000 µs waveform. This value is guaranteed across the full operating temperature range (−55 °C to 185 °C) and defines the highest voltage seen by downstream circuitry during worst-case transient events.
Does PTVS24VP1UTP-QX support bidirectional transient suppression?
No - PTVS24VP1UTP-QX is a unidirectional TVS diode. It clamps only positive transients on the cathode terminal relative to anode (ground). For bidirectional protection (e.g., data lines), a separate symmetric device such as PTVS24VS1UTP-QX is required.
How does thermal resistance affect surge capability in real-world PCB layouts?
Rth(j-a) varies from 60 K/W (ceramic PCB) to 200 K/W (standard FR4), directly impacting junction temperature rise during surge. On standard FR4, a 600 W pulse causes ΔTj ≈ 120 K - so initial Tj must stay below 65 °C to avoid exceeding 185 °C limit. Layout with enlarged cathode copper pour reduces Rth(j-sp) to 12 K/W, improving thermal margin.
Is the SOD128 package compatible with standard reflow soldering profiles?
Yes - the CFP5 (SOD128) package is qualified for lead-free reflow per J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. Figure 7 provides exact solder land dimensions (4.4 mm × 2.1 mm per pad) and stencil aperture guidance for optimal wetting and void control.
